To evaluate the effectiveness and safety of adjuvant anti-VEGF therapy in the surgical treatment of pterygium, and to determine the indications for its use.
MATERIAL AND METHODS
The study included 67 patients (69 eyes) with grade II-IV pterygium. Patients age was 58.8±12.6 years on average. Best corrected visual acuity (BCVA) varied between 0.01 and 1.0 (0.77±0.24). The patients were divided into 3 groups. The first group included 19 patients (19 eyes) with grade II-III pterygium who underwent «bare sclera» surgery and used aflibercept as adjuvant therapy. The second group included 21 patients (21 eyes) with grade II-IV pterygium who underwent auto conjunctival grafting surgery with no adjuvant therapy. The third group included 27 patients (29 eyes) with grade II-IV pterygium who had it removed in combination with single-time peripheral lamellar keratoplasty (PLK) and underwent adjuvant aflibercept therapy.
Among patients who underwent pterygium excision with adjuvant antiangiogenic therapy there were 5 cases (26%) of relapse during the observation period (23.38±8.96 months), among patients after pterygium excision with auto conjunctival plastic surgery - also 5 cases (24%) of relapse, and among patients who underwent LKP combined with anti-VEGF therapy there was only 1 case (3%) of relapse. Astigmatism has decreased by 0.24±0.5 (p=0.052) in the first group, by 1.21±1.0 (p<0.05) in the second group, and by 1.64±1.54 (p<0.05) in the third group compared with pre-surgical values, thus increasing average BCVA in all 3 patient groups by 0.1±0.13, 0.07±0.11 and 0.15±0.15, respectively.
The use of anti-VEGF agents as adjuvant therapy in the surgical treatment of pterygium is a safe method of reducing postoperative inflammation, fibrovascular proliferation and, subsequently, the amount of relapses.
